This is your opportunity to experience Dover’s only Half Marathon Road Race, the COCHECHO CHALLENGE. Dover’s own First Parish Church created this challenging yet accessible, USA Track & Field Certified Half Marathon course that begins at our historic church in the heart of downtown Dover, NH.  After leaving downtown, the course winds through beautiful, rural neighborhoods, crosses over the majestic Cochecho River and then returns to the downtown area for the final push to the finish line at the church. This is Seacoast, NH running at its finest.
